Blown Glass. American Made.

About Us

Founded by Dierk van Keppel in 1991, Rock Cottage Glassworks has been devoted to crafting custom American-made artisan glass.

For over 30 years in the Kansas and Missouri Midwest region, Rock Cottage Glassworks, Inc. has curated an expansive reputation in creating custom public and residential art glass installations. We specialize in large-scale installations and have worked with private stakeholders and residencies, companies, and public art programs to achieve stunning glass works of art.

Rock Cottage Glassworks is also the parent company of its antique mold blown glass lighting line Silica Studio, which started prototyping in 2019 and launched in 2025.
